IMPROVEMENT IN SHUTTER-WORKERS.

Specification forming part of Letters Patent No. 140,217, dated June 24, 1873 application tiled May 17, 1873.

To all whom it may concern:

Be it known that I, HERVEY S. PHILLIPS, of Wilmington, in the county of New Castle and State of Delaware, have invented a new and useful Improvement in Mode of Operating Window-Blinds and Shutters, of which the following is a specification rEhe object of this invention is to provide improved means for opening and closing window-blinds and shutters; and it consists in a bar att-ached to the blind or shutter, in a lever which engages with the bar; and in a curved or circular operating-bar, which en gages with the lever, the construction and arrangement of parts being hereinafter more fully set forth and described.

In the accompanying drawing, Figure ll is a plan view of the entire device, showing the blind closed; also showing the blind open, in dotted lines. Fig. 2 is a view looking from the inside of the window.

Similar letters of reference indicate corresponding parts.

A is the blind or shutter; B is the windowsill. C is the window frame or casing. D is the inner sash. E is a bar of irregular form, or zigzag in shape, having offsets F therein, as seen in Fig. l.' The bar is attached to the inside of the blind or shutter at its ends by means of screws or rivets, or in any suitable manner. G is a lever, which is attached by a pivot or fulcrum screw to the window-sill, as seen at H, so that it may be made to fully The opposite end of this lever is curved, and has lugs I J projecting upward, between which the bar E is placed.

When the lever is moved outward, the bar E slides between the lugs, but there is sntiicient play to allow the offset E to pass without binding, and when the lever is held at rest with the lug J in the angle of one of the off sets, the blind or shutter is held immovable, while by a movement of the lever the lug J slips from the angle, and lug I pushes the bar outward. When the blind is thrown entirely open, as seen in dotted lines, the lug J will rest in the acute angle K, and hold the blind securely in that position, while the lever remains at rest. When the blind is closed this lug J enters the angle or notch L at the other end of the bar, and securely holds the blind closed while the lever is at rest. The blind r shutter may therefore be securely held by the lever when either open or closed, or in three, more or less, intermediate positions. The bar from the angle K, at one end to the angle or notch L at the other, may have any desired number of the offsets or notches F; or it may be made without any, as may be desired, so that the lugs will slide from one end to the other, and simply hold the blind open or closed.

The lever is operated by means of the curved or circular bar M, Which is moved horizontally through the casing above the window-sill from the inside.

N is the handle, which with a portion of the bar projects into the apartment. On the under side of the other end is a recess. On the under side ofthe lever and forming a part of the lever is the drop-bar O, which is received by the recess. P is a staple in the window-sill for guiding the circular bar.

A-s seen in Fig. 1, the blind is closed. Now, when the bar is moved to the right horizontally, it moves on acircle and pushes the lever outward, and the lever pushes the blind outward,r as before stated, thus opening the blind entirely and holding it back against the wall7 or catching in the offset F, and holding it iii any intermediate position. The position of the handle N when the blind is thus held is indicated in dotted lines.

Instead of using the curved bar M for operating the lever, the window may be raised and the lever operated by taking hold of the lug Q. The same effect is produced inv this manner at less expense, but it necessitates the raising of the sash; and I therefore prefer to use the circular bar, or a similar device, by which the blind can be operated from the inside with the window closed.

The advantages of this device for operating window-blinds and shutters are many, and must be apparent to all.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination of the bar E, lever G, 4. The lever G, in combination with angles, and circular bar M, larranlgred to operate suboffsets, notches, or recesses, by means of which stantially as and for the purposes described. a blind or shutter may beheld open or closed,
